Several U.S. and foreign leaders on Sunday leapt to the defense of Canadian Prime Minister Justin Trudeau after he was assailed on Sunday morning talk shows by two of President Trump‘s top advisers.

Both White House economic adviser Larry Kudlow and Trump’s top trade adviser, Peter Navarro, blasted the Canadian leader, sparking criticism from leaders at home and abroad. Politicians focused in particular on comments from Navarro, who laid into Trudeau on “Fox News Sunday” for his pledge to implement retaliatory tariffs on the U.S.

“There’s a special place in hell for any foreign leader that engages in bad faith diplomacy with President Donald J. Trump and then tries to stab him in the back on the way out the door,” Navarro said.
